Oscilloscope Trio Kenwood CS - 1830 servicemanual or schematics urgently needed, please !

My scope from Trio Kenwood is defect. The horizontal deflection ( and delay time, horizontal position etc. .. ) is complete out of order.

Only the X-Y presentation , focus and vertical posiion is functioning.

All fuses and - I think - the complete power supply are o.k. Many semiconducters and elko´s I´ve tested to amd there are no components, which are obviously burned down.
But the item is to complex, to repair it without technical documentation.

So my request is: does anyone have a servicemanual or schematics of this item ? I need it often to test and adjust my equipment.

Thanks in advance of an answer
